PICTURE-DISPLAY IDEYICE.

Specification of Letters Patent.

Patented Sept. 28, 1920.

Application filed July 16, 1919. Serial No. 311,244.

a citizen'of the United States, residing at Paducah, in the county of McCracken and State of Kentucky, have invented certain new and useful Improvements in Picture- Display Devices,jof which the following is a specification, reference being had to the accompanying drawings.

Thisinvention relates to devices for eX-' devices of that character in which a series of pictures or placards are exhibited consecutively at definite intervals of time.

The general object of my invention is to provide a very simple device for this purpose which is operated by power and in which a series of pictures are displayed con-' secutively, the pictures removed from the display opening being disposed rearward of the pictures in front of the display opening so that the pictures travel one by one to the display opening, are displayed for a certain period of time, and then removed therefrom and placed to the back of the other pictures.

A further object is to provide a construction of this character which is particularly capable of use as a means for advertising moving picture shows or plays and in which the front of the casing is designed to display a big picture indicating the general character of the play or moving picture, and in which a series of pictures are presented in consecutive order to illustrate the incidents of the play or moving picture.

A further object is to provide a construction of this character in which a series of holders are provided for receiving the pictures to be displayed so that thepictures may be readily changed.

ther objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a face view of my display 7 device Fig. 5 is a fragmentary section on the line 5-5 of Fig. 2.;

Fig. 6 is a section on the line 66 of Fig. 5;

Fig. 7 is a side elevation of one of the side members 20;

Fig. 8 is an edge View of the members shown in Fig. 7, partly broken away: and

Fig. 9 is a section on the line 9-9 of Fig. 7.

Referring to these drawings, it will be seen that I provide an easel-like stand comprising a front, designated generally 10, which may be made with any ornamental design or form and which incloses an eX- terior frame 11. The back of this case may be of any suitable form and material and is designated 12, and the case is supported with its front upwardly and rearwardly inclined by means of legs 13 or in any other suitable manner. The front 10 is cut out to form a display opening 14-, a display open-- ing 15, and a relatively smaller display opening 16. In the upper display opening a picture 17 is designed to be disposed, this picture resting upon the upper member of a frame which surrounds the opening 15, and being held in place by a latch 18. When this latch is released, the picture may be tilted backward to the dotted line position in Fig. 2 and readily removed and a new picture inserted.

Surrounding the display opening 15 and disposed upon the inside face of this opening is a more or less ornamental frame 19, through which a series of pictures are to be consecutively displayed. Disposed rearward of this frame 19 and mounted thereon are the side pieces 20 which extend parallel to the front of the display casing and are provided with bearings 21 and 22 for upper and lower shafts 23 and 2d. The inner or confronting faces of these members 20 are provided with loi'igitudinally extending slots 25, adjacent their forward edges, which extend for part of the length of the members, and extending parallel to each slot 25, is a groove 26 also on the inside face of the member, which groove is provided at its ends with inclined terminal portions 27 divergently disposed with relation to eachother and intersecting the ends of the slot 25. Extending 5.0 I l I the plctures or holders resting upon the strip from the ends of the slot but disposed on the exterior face of each member 20 are the grooves 28 which extend to the end of the member 20. V

Mounted in the bearings 21 is the shaft 23' and carrying sprocket wheels 29 located in a plane exterior to the outer face of the members 20, and carried upon the shafts 24 are the sprocket wheels 30 of the same slze as the sprocket wheels 29. Passing over these sprocket wheels are the sprocket chains,

belts, or like flexible elements 31. The shaft 24 is a driving shaft, and this shaftcarries atone end" a worm gear wheel 32 driven by a worm 33 mounted on the shaft of anelec tric motor 34; It will thus be seen that the belt, sprocket chain, or flexible connection 31 will' 'constantly rotate in the direction of the arrow in Fig. 2. I

Each chain 31 carries upon. it an inwardly projecting pin 41. There may be one or more of these pins on each chain. Each pin is adapted to project into and travel in the groove 28 and the slot 25.

Coacting with the sprocket chains'are a plurality'of holders 85l1'aving a. size slightly largerthan the opening in the frame 19 and made of sheet metal and having inwardly turned margins or flanges 36 along three sides, formin guides into which pictures of the holder is cut away, at 37, to permit the removal of the picture and each holder, is providedon its side edges adjacent its upper end with laterally projecting pins 38 which are designed to travel in the slots andgrooves 25, 26 and 27. Disposed to extend downward and forward toward the lower member of the frame 19 is a transversely extending strip 39 upon which the several holders with their pictures are supported. in the position shownin Fig. 2.

In the operation of this device, a continuous motion, as before stated, is given to the chains 31. Assuming that the pictures in their holders are arranged as illustrated in Fig. 2, it will be obvious that the trunnions or pins 38 of the several pictures will be arranged in the lowermost, downwardly extendinggrooves 27 with the lower edge of 39. The pictures will thus be arranged one behind the other and the foremost icture will be displayed throughthe opening 15. This picture may be illuminated by means of, an electric light 4E0 mounted within the frame 19 or disposed in any other suitable position. The chains 31 move in a clockwise direction and as the pins 41 move upward along the 'lower portion of the groove 28,- they will reach the;slot.25 and as these.

pins move upward, they will engage beneath the laterally projecting pins 38 of the foremost holder and carrying this holder upward, along the slot 25 until the pins 38 reach the downwardly and rearwardly extending groove 27. Inasmuch as .the pictures cannot be carried any higher, the pins 38 Willslip from their engagement with the pins 32 and the pins 38 will travel down the groove 27. into groove: 26 and so downward to the lowermost groove 27 and behind the pictureswhich are in position for display. Thus, as the carrier composed of the chains 3-1.1novesthrough its path, the pictureswill be picked up one by one and transferred from the 'frontofthe bank of pictures to the rear thereof. The length of time that a picture will be displayed through the opening 115 wi1l, of course, depend 'upon'the rapidity of travel of the chains 31 and the number of pins 41 carried by said chains.

Inasmuch as the pictures can be readily slipped into or out of the holders, it is ob-- viousthat the pictures may be readily changed at anytime desired, the casingbeing provided with a suitable .door in itsback or in any other suitable location to permit access tobe hadto the int'erior'of the casing.

The opening16'will preferably exhibit a V slip or illuminated signor like device showing the date on. which the exhibition is totake-place, though it is obvious that other indicia may be displayed through this opening. device may be used for displaying It may be advertising matter in stores. used" for advertlsingmoving PlCtllIGS and plays, asbefore stated, and 1t isobvlous that the construction might be'modified in many ways and the-deviceusedfor displaying pictures on a relatively large scale.

I claim v V A device of the character described comprising an inclined front member having a display opening, a pair of inclined parallel. guide members disposed behind the display opening in parallel relation thereto, each of saldmembers havmg a portlon of its inner.

surface and one of its front longitudinal edges reduced, a longitudinal marginal flange projectingfromtherear ofthe inner confronting surface of each guide member,

said flange forming.v a guide,.each of said guide members having a slot extending through the marginal edge of its. reduced portion, an endless channel insaidj reduced portion communicating with. the slot, said channel inclining with they guide members,

said guide flange forming one portion of the wall of said" endless channel. ofeach guide member, the other-portionofthe channel communicatingfwith the. slot,.a support extendingubetween said guide:membersin spaced relation to the channel, said'support inclining upwardly from the. lower portion ofthe display o'pening,.picture. holders having trunnions projecting from the. sides thereofand. movable. in said channel, and power operated means adapted to enter the slot and communicating portion of the channel for engagement with the trunnions of the adjacent holder to move said trunnions through the channel, said holder assuming a vertical position after leaving the display opening and traveling in a vertical posltion into engagement with the inclined guide flanges, said guide flanges causing the holder to assume an inclined position and slide down the flanges in back of the preceding holders, said channel cooperating with the 10 inclined support to cause the holders to move toward the display opening.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
